Hi Folks, Got a minor dilemma I'm hoping you guys can help with. I've been mixing with a set of JBL 4312As for the last 10 years, and I really like the tone. Call me crazy! Anyway, the amp I was using was an old Denon (home stereo - multi input - dual speaker channel out) amplifier. I got totally used to mixing with the "Loud" button depressed (I thoroughly expect a tongue lashing from Fats), because of the increased bass at lower mixing levels. Anyway, the amp finally blew up last week in a hail of smoke and fire, and I bought a new Alesis RA300 to replace it. Now, that lovely bass I was used to hearing at low levels is GONE. The Alesis sounds beautiful by the way - clean, clear, with a nice shimmer on the high end, but not the bass response I'm used to. So, I placed a sub woofer (JBL Control SB-5) on a separate channel of my speaker switcher in order to get somewhere close to what I'm used to hearing. I do get an increase in the bass freq's, but not near what I think it should be. Should I - a) retune my ears to the existing acoustics? b) get a separate amp and do the bi-amp thing? or c) get some totally helpful advice from you folks. I'm hoping for "C". What do you guys think?
